What are the best places to buy phones in Dubai?

Dubai offers a variety of places to buy phones, from large retail chains like Carrefour and Lulu Hypermarket to specialized electronics stores such as Sharaf DG and Jumbo Electronics. As someone who moved to Dubai in 2022, I found that prices in the Dubai Mall and Mall of the Emirates are often higher than smaller shops, so it's wise to compare prices online and in-store before purchasing.
